Comparison the Effectiveness of Postoperative Incentive Spirometry and Noninvasive Mechanical Ventilation in Patients Following Craniotomy

Not Applicable

• Conditions: Neoplasms, Intracranial

• Registration Number: NCT02715674
• Lead Sponsor: Istanbul University

Brief Summary

This study will compare the effectiveness of postoperative incentive spirometry and noninvasive mechanical ventilation on pulmonary functions after craniotomy in 60 patients. Patients were randomized into a control group (G-K, n:20), an IS group (G-IS, n:20) and a CPAP (continuous positive airway pressure) group (G-CPAP, n:20)

Detailed Description

This study will compare the effectiveness of postoperative incentive spirometry and noninvasive mechanical ventilation on pulmonary functions after craniotomy in 60 patients. Patients were randomized into a control group (G-K, n:20), an IS group (G-IS, n:20) and a CPAP (continuous positive airway pressure) group (G-CPAP, n:20).

The investigators included male or female, between 18 and 60 years old, American Society of Anesthesiologists score 1, 2 patients in this study. The investigator excluded patients with significant cardiopulmonary disease like myocardial infarction, obstructive or restrictive pulmonary disease, liver or kidney failure, chest wall deformities, postoperative lack of cooperation from this study. In postoperatively, control group will take 4lt/min oxygen with Plasti-med oxygen therapy mask for 6 hours, IS group will carry out Plasti-med TRIFLO 5 min per hour for 6 hours, CPAP group will carry out 10 cmH2O noninvasive continuous positive airway pressure with BIPAP VISION 5 min per hour for 6 hours. Lung functions and arterial blood gas analysis will be recorded preoperative baseline, postoperative 1st, 6th and 24th hours.
